Not being paid on an interior painting job
In Washington, the following parties are entitled to mechanics lien rights: direct contractors, subcontractors, material suppliers, equipment lessors, design professionals, and landscape gardeners for the improvement of real property. In Washington, construction managers and suppliers to suppliers don't have lien rights.
If you are an unlicensed contractor interested in filing a mechanics lien, Washington requires builders to register and obtain a certificate of registration. If you are a "builder" and fail to obtain a certificate of registration, you will lose your right to claim and enforce and lien. Suppliers of materials that don't perform work of incorporating those materials into the project are exempt from these registration requirements.
I hope that helps!
